What is Ably?

Ably ships LiveObjects as production-ready and expands its AI Transport SDK to cover Temporal durable workflows.

Ably is shipping simultaneously across infrastructure SDKs and AI-specific capabilities. LiveObjects — a real-time state sync layer for nested maps and counters — graduated from experimental to production-stable in the Java and Cocoa SDKs this month, with path-based access and resilient subscriptions that survive underlying object replacement. The AI Transport SDK gained Temporal durable-workflow support and OpenAI Responses API streaming. On the infrastructure side, the .NET SDK reduces reconnect latency from 120s to ~25s and the Terraform provider got a major maturity pass with moderation rules and a config importer.

What is MooseFS?

A year of pure maintenance while the 4.x line clears the runway for MooseFS 5.

MooseFS has shipped nothing but maintenance releases across the entire visible window. The last release carrying real capability work was 4.58.0, which fixed partial readdir and added directory-in-parts reading for multi-million-file directories; everything after it is correctness, packaging, and hardening. The 4.59.x releases are single-issue fixes reported by the community and by external security researchers.

Ably ships LiveObjects as production-ready and expands its AI Transport SDK to cover Temporal durable workflows.

◆ Current state

Ably is shipping simultaneously across infrastructure SDKs and AI-specific capabilities. LiveObjects — a real-time state sync layer for nested maps and counters — graduated from experimental to production-stable in the Java and Cocoa SDKs this month, with path-based access and resilient subscriptions that survive underlying object replacement. The AI Transport SDK gained Temporal durable-workflow support and OpenAI Responses API streaming. On the infrastructure side, the .NET SDK reduces reconnect latency from 120s to ~25s and the Terraform provider got a major maturity pass with moderation rules and a config importer.

◆ Where it's heading

The direction is Ably as AI agent infrastructure. LiveObjects' own documentation positions it explicitly for 'AI agents, live configurations, and collaborative experiences.' The AI Transport SDK is a purpose-built layer for agentic workflows — durable sessions, multi-turn conversations, tool execution — layered on Ably's realtime primitives. This is a deliberate expansion from realtime messaging platform into the transport layer that agents run on.

◆ Prediction

The AI Transport SDK will add more model provider codecs — the OpenAI Responses integration suggests Anthropic or Gemini support is next. LiveObjects needs to reach stable across remaining SDKs (Python, .NET) before the feature can be adopted uniformly.

A year of pure maintenance while the 4.x line clears the runway for MooseFS 5.

◆ Current state

MooseFS has shipped nothing but maintenance releases across the entire visible window. The last release carrying real capability work was 4.58.0, which fixed partial readdir and added directory-in-parts reading for multi-million-file directories; everything after it is correctness, packaging, and hardening. The 4.59.x releases are single-issue fixes reported by the community and by external security researchers.

◆ Where it's heading

The line is consolidating rather than expanding. Two signals point the same way: 4.59.1 quietly updated license handling specifically so licenses can be refreshed ahead of MooseFS 5 migrations, and 4.58.4 spent its effort on Fedora spec files and a bootstrap rewrite. That is a project stabilizing a shipping branch and widening distribution while the next major version is built elsewhere.

◆ Prediction

The 4.59.x branch keeps absorbing community bug reports at a low cadence until MooseFS 5 arrives; the license-compatibility work in 4.59.1 is the clearest evidence that migration is the next milestone rather than more 4.x features.
